Super useful, thanks! (I know the original was by CodeManX, but I appreciate the updated version!)

Note, if you try to have it run itself through Console > Run Script it crashes Blender (I learned that the hard way just now) so you might want to look into fixing that if possible.

Also, using this same technique, is there any way to add a button in the Text Editor header to run the current script?
